There’s a new structure showing up this summer in campgrounds bordering national parks, one that offers a higher level of comfort than the typical family camper or pop-up tent. More and more campgrounds are adding cabins to their available accommodations, for while more people are heading to the parks, not all want to sleep on the ground in a tent.

And while cabins long have been part of commercial campgrounds, the latest versions offer many of the comforts of home.

“Many of them are staying in luxurious 'park model' cabins, cottages and other accommodations that feature all the comforts of home,” said Linda Profaizer, president and CEO of the National Association of RV Parks and Campgrounds.

Tents and recreational vehicles still house the majority of those who stay in the campgrounds, but the market seems to be growing for cabins, particularly those that are fully furnished. While not as radical as “glamping” accommodations, those elaborately furnished yurts, the trend in campground cabins is showing up in both independently owned campgrounds and the Kampgrounds of America properties that many travelers are familiar with.

According to industry representatives, roughly one-third of the country’s privately owned campgrounds now offer some form of these comfortable cabins.

Among the KOAs that have added the cabins is the West Glacier KOA outside of Glacier National Park. It added six cabins this spring.

“It’s just crazy,” campground owner Theresa McClure said of the demand for 'park model' cabins, which KOA markets as Kamping Lodges. “We could probably put in 12 and they’d all be booked.”

Ms. McClure said the units are popular because unlike the bare-bones cabins of years past, the Kamping Lodges feature bathrooms, kitchens with full-size appliances, and outside decks with great view and barbecue grills.
